South Portland homeowners in Cumberland County are typically served by Central Maine Power. Central Maine Power customers pay about ~27¢ per kilowatt-hour all-in — supply plus delivery plus riders, not the supply rate on its own. That is the number that decides whether solar is worth it here, because every kilowatt-hour your roof produces is one you stop buying at that price.
The full breakdown is on our Central Maine Power rate page. You can compare it against every other utility in the state on Maine electric rates.
Why Maine rates keep climbing
Every Maine utility buys wholesale power through ISO New England. When capacity and energy prices rise there, they land on Central Maine Power bills and on every other utility in the state at roughly the same time. Demand from data centers is arriving faster than new generation is being built, and that gap is what shows up on your bill — it is not something Central Maine Power sets on its own.
Solar changes the arithmetic because it fixes part of your cost. A power purchase agreement in South Portland means no upfront payment: we install and own the system, you buy the power it produces at a set rate, and you keep buying whatever you still need from Central Maine Power.
What solar costs in South Portland
There is no single number, and any site that gives you one without seeing your roof is guessing. What decides it is your usage, your roof orientation and shading, and the ~27¢ you pay Central Maine Power today. If your roof does not work, we say so on the first call rather than after you sign.
$0-down options are available for qualifying Cumberland County homeowners. The federal residential purchase credit ended for systems bought after December 31, 2025, so anyone still advertising it is running an old ad. What remains in Maine is net metering, and under a PPA the credit stays with the system owner rather than the homeowner.
Common questions from South Portland homeowners
Who is my electric utility in South Portland?
Most of Cumberland County is Central Maine Power territory. Your bill names your utility at the top — if it does not match, call (832) 263-8055 and we will check your address against the service map.
Does solar still make sense now that the federal credit ended?
Under a PPA, yes. The credit belongs to the system owner, which is us, not you — that is what makes $0 down possible. For an outright purchase the math changed in 2026, and we will show you the honest version rather than the brochure version.
What happens if I sell my house?
A PPA transfers to the buyer. We handle the paperwork and the new owner takes over the same rate.
How long does an install take in South Portland?
Installation is typically one to three days. Permits with your municipality and interconnection with Central Maine Power take longer, and we handle both.

Solar Incentives & Net Metering in Maine
Maine's net energy billing (the state's version of net metering) credits homeowners for surplus solar power through Central Maine Power and Versant Power, and Efficiency Maine supports clean-energy adoption. With some of New England's highest electric rates, Maine homeowners often see strong savings from going solar. Net metering is what makes home solar pay off month to month: when your panels make more than you use, the surplus flows to the grid and you earn a bill credit; at night you pull power back and those credits offset it — for a lower, more predictable monthly energy cost.
In Maine, net metering is offered through utilities like Central Maine Power and Versant Power. See the full breakdown on our Maine solar page, or learn why your electric bill keeps rising.
With Maine rates rising, lock in lower power with $0 down.
